I have often used an IWB in small group teachings, but only as a medium for videos and powerpoint presentations. When teaching, I knew there was much more power to unleash from the IWB, if only I knew how to unlock it!
Our ICT tutor, Miles, presented a quick demonstration of IWB tools we can use, then let us loose to create our own IWB presentation.
I created a Food Tech activity, dropping ingredients into a mixing bowl to create cookie dough. It would make an excellent KS2 tool, being visual without being messy: a bonus for a DT lesson!
